Androidで取得した値をメールで確認

Androidで自動で値を収集して、それをレンサバにPOSTして、レンサバから自動でメール送信。

レンタルサーバーの設定

エックスサーバーのcronにスクリプトをフルパスで追加。
/home/xxx/xxx/script
のような感じにして、scriptのパーミッションは701に設定。

スクリプトの実体
tmp=｀cat /xxx/xxx.txt｀
echo “$tmp” | mail -s “title” mail@xxx.com
echo “” > /xxx/xxx.txt

これで、xxx.txtの値を定期送信する。

xxx.txtを作成するためのスクリプトは以下

<?php
class App{
  private function main(){
    if(array_key_exists("key",$_POST) && array_key_exists("lux", $_POST) &&
    $_POST["key"] == "xxx")
    {
      $tmp = file_get_contents("xxx.txt");
      file_put_contents("xxx.txt",$_POST["lux"]."\n".$tmp);
    }
  }
  public function __construct(){
    $this->main();
  }
}
new App;

<?php

class App{

private function main(){

if(array_key_exists("key",$_POST) && array_key_exists("lux", $_POST) &&

$_POST["key"] == "xxx")

{

$tmp = file_get_contents("xxx.txt");

file_put_contents("xxx.txt",$_POST["lux"]."\n".$tmp);

}

public function __construct(){

$this->main();

}

new App;

ここでは単純POSTを受け取ったら作成する。
